Guess the parasite!

So I am taking down a 27G nano salt tank that I didn't get interested in. I bought about 25lbs of live rock and waited to see what appeared.

What I got were those stinging worms and some other pest anemone and this worm/slug thing.

Slug thing

Any ideas as to what these are?

They are not parasites. The first worm in the first video is a bristle worm. The next two might be a echiuran or peanut worm. Look at some pictures. I would throw all of them back into your tank.

I am no longer keeping a marine habitat. I disassembled that tank. The only tank now that has any salt in it, is my brackish setup. The last bristle worm I put in that tank died within a day. (establed tank) .

Thanks for the ID- it was a peanut worm for sure
